North of downtown Fresno, rebar is now being placed for the floor of the box that will carry high-speed trains through the trench alongside the Union Pacific lines and under State Route 180. Under the highway, the support scaffolding is in place for the lid of the box in preparation for a series of concrete pours to form the lid. The walls, floor and lid will all consist of solid concrete, about five feet thick.
